【Vue 開發實戰】實戰篇 # 39：建立一個分步表單

說明

【Vue 開發實戰】學習筆記。

效果

第一步：

第二步：填寫密碼送出

第三步：成功提示

添加 vuex

建立 ​

​ant-design-vue-pro\src\store\modules\form.js​

​

import router from "@/router";
import request from "@/utils/request"
import { message } from "ant-design-vue";

const state = {
    step: {
        payAccount: "kaimo313"
    }
}

const actions = {
    async submitStepForm({ commit }, { payload }) {
        console.log("submitStepForm--->", ...arguments)
        let res = await request({
            url: "/api/form",
            method: "post",
            data: payload
        });
        if(res.data && res.data.message === "OK") {
            console.log("res--->", res)
            commit("saveStepFormData", payload);
            router.push("/form/step-form/result");
            message.success({
                content: "送出成功"
            });
        }
    }
}

const mutations = {
    saveStepFormData(state, { payload }) {
        state.step = {
            ...state.step,
            ...payload
        }
    }
}

export default {
    namespaced: true,
    state,
    actions,
    mutations
}      

import Vue from "vue";
import Vuex from "vuex";
import form from "./modules/form";

Vue.use(Vuex);

export default new Vuex.Store({
    state: {},
    mutations: {},
    actions: {},
    modules: {
        form,
    },
});      

添加 mock form的送出接口

function form(method) {
    let res = null;
    switch (method) {
        case "POST":
            res = { message: "OK" };
            break;
        default:
            res = null;
    }
    return res;
}

module.exports = form;
